Polyflow Agents
Read full descriptionHide full description
Polyflow Agents is a phone client for an AI agent that runs on a computer you own. If you run Hermes — the open-source agent host — this puts that agent in your pocket: the same sessions, the same tools, the same memory, reachable from wherever you are. There is no account to create and no server of ours in the middle. The app connects straight to your host, over your own network or a private tailnet, and sends everything you do to it and nowhere else. TALK TO YOUR AGENT Type a message, dictate one, or send a photo. Replies stream in as the agent writes them, with each tool it uses shown as it runs. Sessions are persistent: pick one up from the list, search across them, rename, pin, or delete. APPROVE THE RISKY BITS When the agent needs permission — to run a command, say — it stops and asks. With the host plugin installed you get a push notification, and Allow or Deny is one tap from the lock screen. Deny sends it back to think again; nothing runs until you say so. EVERYTHING IT MAKES, KEPT Reports, pages, images, and files the agent produces land in Artifacts, ready to open on the phone. Versions are kept when a file is rewritten, so you can see what changed. SEE WHAT IT IS DOING Scheduled jobs, with their last result and next run. Tools and integrations. The model and provider it is set up to use. Logs and events, when you want to know why. SEVERAL AGENTS, ONE AT A TIME A host can run more than one agent. Add a server once and the app asks what it hosts; switch between agents and the whole app re-scopes to the one you picked. WHAT YOU NEED A Hermes host you can reach from your phone — on the same network, or through a tailnet such as Tailscale. Push notifications need a small plugin on the host; the app walks you through installing it, or can send the instructions to the agent to do itself. No host yet? Tap "Try the demo agent" on the first screen. It answers with a scripted conversation, asks for a permission, and produces an artifact, so you can see every screen before you set anything up. WHAT WE DO NOT DO We do not run analytics. We do not collect crash reports. We do not see your conversations, your files, or your credentials — they go to your host and stay there. Your sign-in is kept in the phone's keychain and sent only to the host you gave it to. Polyflow Agents is open source, MIT licensed.

Verdict
